Michael Zhan first traced tea’s journey in 2016, when a chance encounter in a Kunming market led him to a small pu’er cake stamped with a menhai factory number — its wet leaf unfolding a deep amber liquor and the aroma of old wood and apricot pits. That experience rerouted his career. He joined Teamotea as a junior sourcing assistant and spent the next years apprenticed to growers and local procurers, decoding the languages of leaf shape, oxidation, and the telltale compression marks of stone-pressed shēng pǔ’ěr. Today, as the team’s China-based procurement specialist, he moves between Yunnan and Fujian, often spending weeks on the ground during spring and autumn flushes.
His Yunnan side focuses on Lincang and Xishuangbanna prefectures. He has built relationships with families in Bingdao, Yiwu, and Laobanzhang — villages where terraced gardens climb steeply above mists that roll in by mid-morning. A 2019 visit to a Yiwu farmer named Zhang Weiping remains a touchstone: after a 12-hour hike, Michael cupped a freshly pressed gǔshù cake whose silver-furred leaves gave off a scent of wild honey and dried jujube. That lot later anchored a small-batch release on puerh.app, where its tasting notes appeared alongside Michael’s field observations. He trusts Zhang’s meticulous plucking standard, and whenever he needs to verify the source of a claimed gǔshù lot, he returns to those same ridges to compare leaf morphology and soil colour.
In Fujian, Michael is just as at home among the rocky peaks of Wuyishan and the rolling terraces of Anxi. He has sourced traditional Tiě Guān Yīn from a master named Chen Wenbin, whose sixth-generation family workshop still uses 12-hour basket-rolling. The infusion of a well-made autumn harvest there blushes pale chartreuse, with a mouthfeel that coats the tongue like cool silk. For darker yán chá, Michael often visits a small collective near the Tianxin temple, where charcoal roasting fills the lanes with a sweet, biscuity smoke. He will cup dozens of Dà Hóng Páo samples in a single day, noting the balance of roast, mineral spine, and the particular ‘yányùn’ — the rock rhythm — that marks true zhengyan material.
All this ground-level work led to the design of his signature service on tea.support: the Sourcing claim — provenance verification. When a tea brand, collector, or enthusiast needs to confirm that a cake claimed as 2003 Menghai shú was indeed pressed at that factory, Michael dives into lot codes, humidity records, and his network of contacts. He cross-references tasting notes, compares leaf grade and fermentation depth, and often conducts a blind cupping against known reference samples. The wet leaf after a flash rinse can tell as much as the label — if the fermentation smells purely of earth and old books without an artificial overlay, that’s a good sign. Every verification ends with a detailed report, not a certificate, because he believes transparency is a process, not a stamp.
Michael’s expertise also surfaces elsewhere in the constellation. He contributes monthly cupping reports to puerh.app, where he is known for his precise, no-frills tasting language and for flagging batch inconsistencies. On tea.school, he teaches a hands-on module on field procurement, walking students through the practical steps of visiting a tea mountain, from negotiating at the village gate to reading a plucking order. Occasionally he hosts an informal lot evaluation on tea.community, sharing screen and palate with members who bring their own mystery cakes. His cross-site work reinforces the same idea: that sourcing is not romance but rigorous, repeatable observation.
Off the mountain, Michael is a quiet advocate for long-term relationships over transactional buying. In his view, the most reliable provenance comes from walking the same rows season after season, watching how a single plot’s character drifts with rainfall and soil health. That patience informs every lot he selects and every claim he helps verify. The colour of a liquor, the texture of spent leaves, the first aroma off a dry leaf — these are the data points that matter when the label is ambiguous.
